One of the joys of this is how easy and quick it is to make. You may need to be rather brutal with the lettuce as you tear the leaves off to provide the edible wrappers for the beef, which is why I specify one to two icebergs. If you want to perk the leaves up a little, making sure they curve into appropriate respositories for later, leave them in a big bowlful of very cold water (throw in ice cubes too) while you cook the minced beef, then make sure you drain them well before piling them up on their plate. For US cup measures, use the toggle at the top of the ingredients list.
